This invention relates to coin display holders and is directed moreparticularly to that type of holder which can be combined in book formby means of binder screws or which can be inserted into a loose leafcover of conventional design.

In displaying coins it is customary to have both sides of the coinvisible through transparent protective covers which allow minuteexamination, yet which protect the coin against handling andmisplacement or loss. This invention is directed to a new and novel wayof mounting a number of coins in preformed apertures over which atransparent slide can be afiixed on each side, the entire displayforming a neat, attractive and durable sheet with flush surfaces whichcan be combined with other similar sheets in the manner of pages in anotebook. All the parts of the display holder can be molded frompolyethylene plastic or other suitable material.

In the accompanying illustration, which is a part of the description:

FIGURE 1 is a general perspective view of one of the display holders.

FIGURE 2 is a partial horizontal cross section of the holder.

FIGURE 3 is an enlarged detail of a vertical cross section.

FIGURE 4 is a perspective detail of the binder strip comprising a partof each holder.

FIGURE 5 is a perspective detail of one corner of the holder body whichlocks into the binder strip.

FIGURE 6 is a perspective detail of an alternate form of the holderbody.

FIGURE 7 is a partially cut away detail of a number of holders bound innotebook form.

In the preferred form of the invention the assembled holder 10 consistsof a main body 11 molded, or otherwise formed, from either transparentor opaque plastic and having in each surface a number of shallowhorizontal channels 12 so disposed that the opposite channels on thefront and back of the body are aligned to form a web 13 slightly thickerthan the coins to be displayed. Each such web contains variou sizes ofapertures 14 into which coins or similar objects can be inserted.

The edges of the channel 12 are undercut to receive the similarly shapededges of a set of transparent slides 16 which match the sizes of thevarious channels 12 and are also molded or formed from a suitableplastic. These transparent slides 16 are of a thickness equal to thedepth of the channels 12 so that when they are in place the bodyassembly presents a smooth surface without ridges or grooves. Each slide16 has on its inner surface near the inner end a detent 16a which snapsinto a corresponding dimple 16b in the bottom of the channel 12 to holdthe slide 16 in place while the body 11 is detached from the hinge trip17, referred to hereinafter.

To complete the holder assembly 10, a hinge strip 17 is slidablyattached to the body 11 by means of a dovetail joint 18 running alongone edge 19 of the body 11 which engages a matching channel 20 in theadjacent edge 21 of the hinge strip 17. The base of this dovetail 18consists of a shoulder 18a which the edge 21 of the hinge strip 17 fitsagainst. One end 22 of each slide 16 is finished square to bear againstthis shoulder 18a when the slide is inserted all the way into thechannel 12 so that when the slides 16 are in place and the hinge strip17 is slid upwardly from the bottom of the body 11 along the dovetail18, the holder 10 i smooth and continuous on all sides except for theraised ridges 11a on the body 11 and 17a on the hinge strip 17 whichprotect the surface of the slides 16 from contact with each other andconsequent abrasion. If preferred, the ridges 16 may extend across thetop and bottom only. Each hinge strip 17 has a thinned portion 17brunning its length which is flexible enough to allow the bound holders10 to be opened like a book as shown in FIGURE 7.

A stop 23 is molded or formed on the top corner of the body 11 which isreceived by a cutout 24 on the hinge strip 17. This keeps the body 11located in relation to the hinge strip 17 and prevents the pagescomposed f the body 11 and the slides 16 from accidentally falling outof the hinge strip. The hinge strip 17 is supplied with holes 25 intowhich can be inserted binder screws 26 to make up the holders 10 intohooks, or the holders can be bound similarly into a standard loose leafcover 27 which can be tilted or decorated. FIGURE 5 shows a portion ofone of the slides 16 as it is withdrawn from the channel 12 past thedovetail 13 after the hinge strip 17 has been removed.

The advantages of this type of coin display holder are readily apparent.It is a simple matter to remove one body from the hinge strip and thenremove one or more slides for access to the coins, and until the body isremoved from the hinge strip the slides are locked in place. Whileaccess to the coins or coin apertures is relatively simple, it cannot beaccomplished without an easily detected manipulation and removal of theWhole assembly, thus discouraging pilfering. The insertion of a screw 28into a threaded hole in the dovetail joint makes it even more difiicultfor unauthorized persons to remove a coin unnoticed. The flush surfacesof the assembled holder have already been described, and these addgreatly to the appearance of the display and facilitate keeping itclean.

In a modified form of the invention shown in FIGURE 6 the channels 12are continued through the dovetail joint 18 making it possible to use athinner web 13 and hence a thinner body 11, making the entire displaymore compact.

The invention is not limited to the construction herein shown anddescribed, but may be made in many ways within the scope of the appendedclaims.

What is claimed is:

l. A coin display holder comprising a flat rectangular body, a hingestrip slidably dovetailed to one edge of said body, said hinge striphaving a lengthwise thinned portion for hinge line flexibility, opposedparallel channels in the respective surfaces of said body andperpendicular to said hinge strip, said channels being open at the endadjacent said hinge strip and closed at the opposite end, said channelsforming a web therebetween slightly thicker than the coins to bedisplayed, perforations in said webs to receive said coins, transparentslides fit ting into said channels and covering said perforations, oneend of each said slide abutting the edge of said hinge strip, and holesin said hinge strip positioned for receiving retainers.

2. A coin display holder of fiat rectangular shape comprising a hingestrip having holes for retainers, a body containing aligned rows ofperforations to receive the coins to be displayed, a sliding dovetailjoint connecting said hinge strip and said body, shallow channels withundercut edges in the front and back surfaces of said body, saidchannels being paired front and back to form a web along said rows ofperforations, said channels running perpendicular to said dovetail jointand being open L) at the end adjoining said joint and closed at theopposite end, transparent slides fitting lengthwise into said channelsand retained therein by said undercut edges of said channels, each saidslide being of a length to butt against the edge of saidbinderstrip.

3. A coin display holder as described in claim 2 having at thevtop endof. said sliding dovetail joint on said body a laterally projectingstopand a matching cutout at the top end of said sliding dovetail jointon said binder body by sliding in one directiQn, nly.
